COT-BED.

Specification of Letters Patent.

Patented Aug. 14, 19,17.

Application filed .T une 8, 1916. Serial No. 102,454.

To all 107mm 'it may concern:

Be it known that I, NATHAN KAPLAN, a citizen of the United States, residing at No. 359 Madison street, in the borough of Manhattan, city of New York, county and State of New York, have invented a new and useful Cot-Bed, of which the following is a specification. i

My invention relates to improvements in collapsible cot beds, and it consists in the novel features hereinafter more fully described.

The objects of my improvements are:

First: To provide a collapsible cot bed with a minimum number of parts, which cot bed can be readily taken apart and the parts folded to occupy very little space.

Second: To have the joints of said cot bed and sundry details thereof of a novel, very efficient construction.

Third: To have said construction simple, durable and inexpensive.

I attain these objects by the devices illus` trated in the accompanying drawings or by any mechanical equivalent or obvious modification of the same.

In the drawings,

Figure 1 is a side view of the collapsible cot bed shown as assembled.

Fig. 2 is an end View of the assembled cot bed.

Fig. 3 is a sectional view of a detail of the joint of the sections 11 and 11a of one of the bearer bars hereinafter described, the section being taken in a horizontal plane, parallel to the line E F of Figs. 4 and 5 and close to the rivet 24 without cutting the same.

Fig. 4 is a section on the lineV C-D of Fig. 3.

Fig. 5 is a section on the line A--B of Fig. 3. v

Fig. 6 is an end elevation of the end of one of the cross legs 12 of the cot bed, showing the connection of the cross legl 12 tothe bars 11 and to the link 25, hereinafter described, and showing also a cross-section of said link 25 on the line G-H of 7.

Fig. 7 is a side elevation of the link 25.

Similar numerals and letters refer to similar parts throughout the several views of the drawings, as follows:

' 11, 11L and 11b are the sections of each of the two bearer bars serving as a support for the canvas sheet 16, which is suspended from said bars by means of the sockets 16a, as shown in Fig. 2. v

Said sections 11, 11a and llbrof each bearer bar are jointed at their 'contiguous ends in such a manner that they maybe folded up when the bar is removed from said socket 16a.V Y

12 is each of a pair of cross legs, shown in Figs. 1 and 2 as supporting the bearer bars above described'.

18 are strips ofpantographs shown in Figs. 1 and 2 as kconnecting the pairs of cross-legs 12, 12 on each side thereof.

14, 14 are steel brackets shown as secured each to the lower end of one of the crosslegs` 12 by means of suitable set-screws, pivotally connected to the lower end of a corresponding pantograph strip by means of one of the links 25, shown in detail in Figs.y 6 and 7.

15, 15 are steel brackets shownas secured each to the upper end of a crosselegy 12 by means ofsuitable rivets and pivotally connected to the upper end Vof a'corresponding pantograph strip by means of one of said links 25, which is 'shown in Fig. 6 as straight; but which may also be bent, if desired.

' Thevbracket 15 has at its upper end an extension shown in Figs. 2 and 6 as passing through the loops of the U-shaped bolt 19 secured to said bars 11, 11a or 11b, thereby d'etachably connecting each of saidrcross legs Y 12 tosaid bars 11, 11? or 11b.

. 17 is a pin, which is shown in Figs. 1 and ally connecting each pair of said pantograph strips 18. f

20 is a pin shown in Figs. 1 and 2 as connecting each end of said pantograph strips '13 to said link 25. v

The other end of said Vlink 25 is inclosed by the corresponding endv of eachof said brackets 14 and 15, each of which ends is bent inwardly, as shown in detail in Fig. 6 which shows the construction of the lower end of the bracket 15; the uppery end of the bracket 14 has the same identical construction as the lower end of the bracket l5, but it is not shown in a separate detail view. j

21, 21 are side strips shown in Fig. 3 as secured to each side of each of the inner ends of said bar sections 11,`and 11a by means of the double rivet 23. The inner ends of said strips 21 are cut circular shown in Figs. 4 and 5.

22 is a center piece or hinge shown in Figs. 3, 4 and 5 as pivotally connected to said side strips 21 by means of the pins 24 passing through the ends of said bars 11 and 11a, which are shown as cut away on the sides to make room for said strips 21 and the inner flaps of said hinges 22, which inner iaps are shown as extending only through the middle part of the length of the flanges and they are bent over at their edges to come in contact with the outer flaps of said flanges, as shown in Fig. 5.

The bar sections 112N and 11b are connected by a center piece or hinge which is similar to the hinge above described, but adapted to close in a direction opposite to that in which the former hinge is adapted to close, thereby enabling said bearer bars to be folded up.

vWhen the bars 11 are inserted into the sockets 16EL of the canvas sheet 16 they are revolved therein until the loop of the double bolt 19 is opposite a suitable slot in the socket 16a, through which slot said loop is made to pass, whereupon a suitable leather shield vmay be placed over said loop to protect the socket 16CL from being worn and torn by thev upper end of the cross-leg 12 and bracket 15 in contact therewith, for which purpose said leather shield may be also provided with asuitable slot.

The leather shield may be of the usual oval or elliptical shape, and I prefer to have said shield placed with its length transversely to said bar 11 instead of longitudinally thereto; said shield may be secured to said bar by means of two set screws, and the bar is then connected to each of said strips 15 as above described.

By means of the construction of the brackets 14 and 15 as shown and the link 25I connected thereto I avoid the use of universal joints for connecting the cross legs of the cot bed to the pantograph strips.

The method of forming the joint at the inner ends ofthe bar sections 11 and 11a is also novel and of great merit, particularly the construction of the hinge 22.

Many changes could be made in the form of construction of the details of my collapsible cot bed within the scope of my invention.

I do not therefore, restrict myself to the exact shape of the details as shown, but I wish to include also all mechanical equivalents and obvious modifications thereof.

What I claim as my invention and desire to secure by Letters Patent, is

1. In a collapsible cot bed comprising 'a fabric sheet, a pair of bearer bars, crosslegs, 4arranged in pairs transversely to said cot bed, and pantographs, connecting said pairs of cross legs, said pantographs being placed lengthwise to said cot bed, and each of said pantographs consisting of a pair of strips collapsibly connected to said cross legs, a means for collapsibly connectino' said strips to said cross legs, comprising suitable links pivotally connected to said strips, brackets secured to said cross legs near their ends, one end of each of said brackets being bent inwardly toward said cross leg, as shown, thereby forming a bearing for said links.

2. In a collapsible cot bed a flexible sheet, a pair of bearer bars, consisting each of a number of sections adapted to be folded, suitable sockets at the sides of said sheet, adapted to inclose said bars, suitable supports for said bearer bars, and collapsible joints for the contiguous inner ends of said sections, each joint comprising a pair of side plates for the end of each contiguous bar section and a center piece or hinge, pivotally connected to each contiguous pair of said side plates, said center piece consisting of a T shaped plate bent over through an angle of 180, the bend being on the broad leg of the T and adjacent to the narrow leg thereof, said center piece being placed with said bend under said side plates, with said broad leg outside of said side plates and the end of said narrow leg being bent outwardly toward said broad legof said centerpiece, thereby forming the central part of said hinge, the inner ends of said side plates being cut circular, and the central part of each of said hinges being adapted to cooperate with said side plates and to act as a stop to keep the sections of said bearer bars, when folded up, from passing the position of perpendicularity to their original position.
